Probing Kirkwood-Dirac nonpositivity and its operational implications via moments
Sudip Chakrabarty, Bivas Mallick, Saheli Mukherjee +1
The Kirkwood-Dirac (KD) distribution has recently emerged as a powerful quasiprobability framework with wide-ranging applications in quantum information processing tasks. In this w…
